Kia Sedona Turn Signal Bulb Size

Additional Notes

• The Kia Sedona front turn signal uses the 2357NA bulb across the 2006-2021 model years, with the exception of 2015-2017, making it the most consistently specified bulb type in these front turn signal listings.
• The 2357NA is a dual-filament, 12V bulb rated at 26.9W on its high-intensity filament and 8W on its low-intensity filament, fitted with a BAY15d bayonet base and natural amber glass coloring.
• The natural amber glass of the NA-suffix bulbs produces the amber turn signal color directly from the glass envelope rather than relying on an amber-tinted lens housing, which is a relevant fitment consideration when the housing itself is clear.
• The Kia Sedona rear turn signal uses the 1156NA across the 2002-2014 model years, making it the most widely specified rear turn signal bulb in these listings.
• The 1156NA is a single-filament bulb, unlike the dual-filament front turn signal bulbs. It operates at 12V with a 21W output and uses a BA15s bayonet base, which is not interchangeable with the BAY15d base found on dual-filament bulbs despite their similar appearance.
• The BA15s and BAY15d bases differ in pin alignment. The BA15s base has two pins positioned at the same height, while the BAY15d base has offset pins to prevent incorrect installation of a single-filament bulb in a dual-filament socket.
• The 2004 Kia Sedona front turn signal specifies the 1034NA rather than the 1157NA used in the 2002, 2003, and 2005 model years. The 1034NA is described as a variant of the 1157 and shares the same BAY15d base and 12V, 21W/5W ratings.
• The 2357NA and 2357 bulbs share identical wattage ratings of 26.9W/8W and the same BAY15d base, with the primary distinction being that the 2357NA carries natural amber glass while the 2357 does not. The 2357 is specified for the Sedona rear turn signal in the 2018-2021 model years.
• The 1157NA and 2357NA are both dual-filament BAY15d bulbs, but the 2357NA draws more power on its high-intensity filament at 26.9W compared to the 1157NA at 21W, making them functionally distinct despite sharing the same base type.
• All bulb types listed across both the front and rear turn signal positions conform to ANSI standards applicable to the United States and Canada.
